Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving boiler steam generators, and more particularly, to a boiler vehicle steam generator with a double pipeline. Background Art

[0002] A boiler vehicle steam generator is a device that recovers waste heat through an energy-saving waste heat boiler and supplies it to the steam generator, and can produce steam for use in other processes. This type of equipment is usually designed to be compact and suitable for mobile or portable scenarios.

[0003] In order to improve the efficiency of steam generation, a double U-shaped loop pipeline steam generator is used in some energy-saving boilers. When the heat source enters the boiler from one side of the boiler to heat the pipeline, due to the small distance between multiple bending sections of the double U-shaped loop pipeline, after the heat source passes through the U-shaped loop pipeline closer to the heat source, it cannot heat the U-shaped loop pipeline farther from the heat source well. The heating effect on the side of the U-shaped loop pipeline farther from the heat source is even more unsatisfactory, resulting in insufficient heating effect of the U-shaped loop pipeline farther from the heat source. And when the U-shaped loop pipeline closer to the heat source stops operating and the U-shaped loop pipeline farther from the heat source operates alone, the heat conduction efficiency of the heat source through the stopped U-shaped loop pipeline to the operating U-shaped loop pipeline is insufficient, resulting in an increase in the power of the heat source when heating the operating U-shaped loop pipeline, increasing energy consumption.

[0004] To solve the above problems, the inventor has proposed a boiler vehicle steam generator with a double pipeline. Summary of the Invention

[0005] To solve the above technical problems, a boiler vehicle steam generator with a double pipeline is provided.

[0006] To achieve the above object, the present invention can adopt the following technical solutions:

[0007] The present invention provides a boiler vehicle steam generator with a double pipeline, including: a base, a boiler fixedly connected to the top of the base, and a double-tube evaporation assembly disposed inside the boiler;

[0008] The double-tube evaporation assembly includes a first ring symmetrically and fixedly installed in the boiler. Two first sliding rods are symmetrically and fixedly connected between the two first rings. Two first rotating rods are symmetrically and rotatably connected between the two first rings. Two electric telescopic rods are symmetrically and fixedly installed at the inner bottom of the boiler. Two second rings are symmetrically arranged in the boiler. The telescopic ends of the two electric telescopic rods are fixedly connected to the lower second ring together. Two second sliding rods are symmetrically and fixedly connected between the two second rings. Two second rotating rods are rotatably connected between the two second rings together.

A plurality of first sliding seats are sleeved on each two adjacent first rotating rods and first sliding rods. A plurality of second sliding seats are sleeved on each two second sliding rods and second rotating rods.

[0009] Preferably, four upper threads are in a group, and four lower threads are in a group. A group of upper threads and lower threads are symmetrically arranged on the first rotating rod and the second rotating rod.

[0010] Preferably, the plurality of first sliding seats are threadedly connected to the first rotating rod through the upper threads and the lower threads. The plurality of second sliding seats are threadedly connected to the second rotating rod through the upper threads and the lower threads.

[0011] Preferably, rotating sleeves are rotatably connected to both the first sliding seat and the second sliding seat. Evaporation tubes are sleeved inside the rotating sleeves. The rotating sleeves and the evaporation tubes are arranged obliquely.

[0012] Preferably, the evaporation tube is semi-circular arc-shaped.

[0013] Preferably, a rotating connection assembly is arranged on the evaporation tube. The rotating connection assembly includes a fixed tube fixedly connected to the bottom end of the evaporation tube. A connecting tube is fixedly connected to the side of the fixed tube away from the evaporation tube. A ball sleeve is fixedly connected to the top end of the evaporation tube. A ball joint is rotatably connected inside the ball sleeve. One end of the connecting tube away from the fixed tube is fixedly connected to the ball joint. A through hole is opened on the ball joint.

[0014] Preferably, the connecting tube is communicated with the through hole. The through hole is communicated with the top end of the evaporation tube.

[0015] Preferably, a dislocation assembly is arranged at the inner bottom of the boiler. The dislocation assembly includes a first motor fixedly installed at the inner bottom of the boiler. A first pulley is fixedly connected to the output end of the first motor. A second pulley is rotatably connected to the side of the bottom of the first ring away from the first pulley. A first belt is sleeved on the first pulley and the second pulley together. A second motor is fixedly installed at the inner bottom of the boiler. A third pulley is fixedly connected to the output shaft of the second motor. A fourth pulley is rotatably connected to the side of the bottom of the second ring away from the third pulley. A second belt is sleeved on the third pulley and the fourth pulley together.

[0016] Preferably, the bottom ends of the two first rotating rods pass through the first ring and are respectively fixedly connected to the first pulley and the second pulley.

[0017] Preferably, sliding grooves are formed at the bottoms of the two second rotating rods. Sliding rods are fixedly connected to the tops of the third and fourth pulleys. The top ends of the two sliding rods pass through the second ring, and one end of the two sliding rods passing through the second ring is slidably connected to the sliding groove. Limiting grooves are symmetrically formed at the bottoms of the two second rotating rods. Every two limiting grooves form a group, and the two groups of limiting grooves are respectively communicated with the two sliding grooves. Limiting blocks are symmetrically and fixedly connected to the two sliding rods, and the two groups of limiting blocks are respectively slidably connected to the two groups of limiting grooves.

[0018] As described above, the characteristics and advantages of a steam generator for a boiler vehicle with double pipelines in the present invention are as follows:

[0019] By providing the threaded inner and outer double-pipeline evaporation tubes, compared with the U-shaped ring evaporation tubes, the heat transfer efficiency is higher, resulting in a higher steam generation efficiency. Moreover, different steam usage requirements can be met by switching the double pipelines, avoiding the risk of the entire system shutting down due to a single pipeline failure, thereby ensuring the stability and safety of the system. At low loads, one of the pipelines can also be closed, thus saving fuel consumption and reducing operating costs to cope with the limited energy in the boiler vehicle.

[0020] Through the settings of the upper thread and the lower thread, the evaporation tubes can move equidistantly upward and downward, causing the distances between multiple evaporation tubes to increase synchronously. After pulling the pipelines apart by a certain distance, the hindrance effect of adjacent pipelines on heat conduction will decrease, and there will be more sufficient space for heat to diffuse, enabling heat to be more evenly transferred to each pipeline position, achieving the effect of improving the steam generation efficiency under the condition of unchanged input power.

[0021] Through the setting that the outer pipeline evaporation tubes can be adjusted in height, after adjusting the distance between the inner and outer double pipelines, the evaporation tubes of the outer pipeline can move vertically to further stagger the evaporation tubes of the inner pipeline and the outer pipeline, further improving the heating effect of the hot air flow on the double pipelines and achieving the effect of energy-saving steam generation.

[0022] Through the lifting of the outer pipeline evaporation tubes, in the state where the external pipeline is out of use, the external pipeline can be lifted or lowered according to the adjustment of the distance between the internal pipelines, enabling the evaporation tubes on the external pipeline to avoid the evaporation tubes on the internal pipeline and preventing the evaporation tubes on the external pipeline from blocking the hot air flow. Thus, when operating with a single pipeline, the heat conduction efficiency inside the boiler is ensured, and the situation where the external pipeline blocks the internal pipeline, resulting in insufficient heating efficiency and the need to increase the heating power, is avoided, further achieving an energy-saving effect on steam generation.

[0038] As Figures 1 to 10 shown, an embodiment provided by the present invention, a steam generator for a boiler vehicle with a double pipeline will be elaborated in detail below:

[0039] A steam generator for a boiler vehicle with a double pipeline, as Figures 1 to 6 shown, includes: a base 1, a boiler 2 is fixedly connected to the top of the base 1, a fan system and a burner are arranged on the side of the boiler 2 for heating the pipeline inside the boiler 2. The fan system and the burner are prior arts and will not be described in detail. A double-pipe evaporation assembly is arranged inside the boiler 2;

[0040] The double-tube evaporation assembly includes a first ring 301 symmetrically and fixedly installed in the boiler 2. Two first slide rods 302 are symmetrically and fixedly connected between the two first rings 301. Two first rotating rods 303 are symmetrically and rotatably connected between the two first rings 301. Two electric telescopic rods 304 are symmetrically and fixedly installed at the inner bottom of the boiler 2. Two second rings 305 are symmetrically arranged in the boiler 2. The telescopic ends of the two electric telescopic rods 304 are fixedly connected to the lower second ring 305 in common. Two second slide rods 306 are symmetrically and fixedly connected between the two second rings 305. Two second rotating rods 307 are rotatably connected in common between the two second rings 305. Upper threads 308 and lower threads 309 are symmetrically arranged on the two first rotating rods 303 and the two second rotating rods 307. Four upper threads 308 form a group, and four lower threads 309 form a group. A group of upper threads 308 and lower threads 309 are symmetrically arranged on the first rotating rod 303 and the second rotating rod 307. A plurality of first sliding seats 310 are sleeved on each two adjacent first rotating rods 303 and the first slide rods 302. The first sliding seats 310 are all slidably connected to the outer wall of the first slide rod 302.

And the upper threads 308 and the lower threads 309 are arranged in the opposite direction. The upper threads 308 and the lower threads 309 can drive the plurality of second sliding seats 311 and the first sliding seats 310 distributed up and down to move away from each other. The number of the first sliding seats 310 and the second sliding seats 311 is odd. The middle parts of the first rotating rod 303 and the second rotating rod 307 are not provided with the upper threads 308 or the lower threads 309. The middle first sliding seat 310 and the second sliding seat 311 are fixedly connected to the first slide rod 302 and the second slide rod 306. Rotating sleeves 312 are rotatably connected to both the first sliding seat 310 and the second sliding seat 311. Evaporation tubes 313 are sleeved in the rotating sleeves 312. The evaporation tubes 313 can move and displace in the rotating sleeves 312. And the rotating sleeves 312 are made of rubber material and will not cause wear when pulling the evaporation tubes 313 to transfer and rotate. The evaporation tubes 313 are semicircular arcs, and the rotating sleeves 312 and the evaporation tubes 313 are arranged obliquely.

[0041] It should be noted that the evaporation tubes 313 respectively connected to the plurality of rotating sleeves 312 on the first sliding seat 310 and the second sliding seat 311 in the figure form two inner and outer evaporation tubes 313. And in the figure, for the convenience of seeing the structure clearly, it is only an example diagram. The distance between the actual multiple evaporation tubes 313 is relatively close and dense in the prior art, similar to a spiral spring shape.

[0042] Furthermore, as Figure 5 and Figure 7As shown in the figure, a rotating connection component is provided on the evaporation pipe 313. The rotating connection component includes a fixed pipe 401 fixedly connected to the bottom end of the evaporation pipe 313. One side of the fixed pipe 401 away from the evaporation pipe 313 is fixedly connected with a connecting pipe 402. The top end of the evaporation pipe 313 is fixedly connected with a ball socket 403. A ball joint 404 is rotatably connected inside the ball socket 403. One end of the connecting pipe 402 away from the fixed pipe 401 is fixedly connected with the ball joint 404. A through hole 405 is provided on the ball joint 404. The connecting pipe 402 is communicated with the through hole 405, and the through hole 405 is communicated with the top end of the evaporation pipe 313. The ball sockets 403 are not provided at the top ends of the two evaporation pipes 313 at the topmost part for discharging steam. The fixed pipes 401 are not provided at the bottom ends of the two evaporation pipes 313 at the bottommost part for inputting water.

[0043] Further, as Figure 3 and Figures 8 to 10 shown in the figure, a dislocation component is provided at the inner bottom of the boiler 2. The dislocation component includes a motor one 501 fixedly installed at the inner bottom of the boiler 2. A pulley one 502 is fixedly connected to the output end of the motor one 501. A pulley two 503 is rotatably connected to one side of the bottom of the ring one 301 away from the pulley one 502. A belt one is sleeved on the pulley one 502 and the pulley two 503. The bottom ends of the two rotating rods one 303 pass through the ring one 301 and are respectively fixedly connected with the pulley one 502 and the pulley two 503. A motor two 504 is fixedly installed at the inner bottom of the boiler 2. A pulley three 505 is fixedly connected to the output shaft of the motor two 504. A pulley four 506 is rotatably connected to one side of the bottom of the ring two 305 away from the pulley three 505. A belt two is sleeved on the pulley three 505 and the pulley four 506. Sliding grooves 507 are provided at the bottoms of the two rotating rods two 307. Sliding rods 508 are fixedly connected to the tops of the pulley three 505 and the pulley four 506. The top ends of the two sliding rods 508 pass through the ring two 305. One end of the two sliding rods 508 passing through the ring two 305 is slidably connected with the sliding grooves 507. Limiting grooves 509 are symmetrically provided at the bottoms of the two rotating rods two 307. Every two limiting grooves 509 are in a group. The two groups of limiting grooves 509 are respectively communicated with the two sliding grooves 507. Limiting blocks 510 are symmetrically fixedly connected to the two sliding rods 508. The two groups of limiting blocks 510 are respectively slidably connected with the two groups of limiting grooves 509.

[0044] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments:

[0045] The initial state is:

[0046] The two rings two 305 are at the same height as the ring one 301, and the two rotating rods one 303 and the two rotating rods two 307 are not rotated.

[0047] The working state is:

[0048] Double-tube evaporation:

[0049] When generating steam, preheated water is input into the two bottommost evaporation tubes 313 from the bottom of the boiler 2. After the water enters the evaporation tubes 313, it enters the through hole 405 through the ball sleeve 403 and the connecting pipe 402, and then enters the evaporation tubes 313 at the other end through the connecting pipe 402 and the fixed pipe 401. During the process of the water moving upward through multiple evaporation tubes 313, the burner on the side of the boiler 2 cooperates with the fan to heat and evaporate the water in the multiple evaporation tubes 313. The steam generated by evaporation is discharged from the two topmost evaporation tubes 313 into the steam collection pipeline, thus achieving the effect of simultaneous evaporation of the double pipelines.

[0050] Adjusting the spacing:

[0051] During the process of generating steam, the first motor 501 can be started, so that while the first motor 501 drives the first pulley 502 to rotate, it also drives the second pulley 503 to rotate. The first pulley 502 and the second pulley 503 drive the two first rotating rods 303 to rotate synchronously. When the first rotating rods 303 rotate, with the centered first sliding seat 310 as the center, the first sliding seat 310 located above the centered first sliding seat 310 moves upward under the action of the thread of the upper thread 308 and the limiting action of the first sliding rod 302, and the first sliding seat 310 located below the centered first sliding seat 310 moves downward under the action of the thread of the lower thread 309 and the limiting action of the first sliding rod 302. Under the action of multiple upper threads 308 and lower threads 309, multiple first sliding seats 310 achieve synchronous variable pitch. During this process, since the spacing between the evaporation tubes 313 becomes larger, the rotating sleeve 312 and the evaporation tubes 313 rotate under the connection action of the ball sleeve 403 and the ball joint 404. The fixed pipes 401 at the bottom ends of the multiple evaporation tubes 313 drive the ball joints 404 to rotate in the ball sleeves 403 through the connecting pipes 402, so that after the spacing and angle of the evaporation tubes 313 change, the water and steam can still enter the next section of evaporation tubes 313 through the through hole 405, the connecting pipe 402 and the fixed pipe 401, achieving the effect of increasing the spacing between the inner ring evaporation tubes 313 during steam generation. After the pipelines are pulled apart by a certain distance, the hindering effect of adjacent pipelines on heat conduction will decrease, and there will be more sufficient space for heat to diffuse, enabling the heat to be more evenly transferred to each pipeline position, making the multiple evaporation tubes 313 heat more evenly and the heating effect of the water flow in the evaporation tubes 313 better, so as to improve the efficiency of steam generation.

[0052] Offset adjustment:

[0053] After adjusting the distance between the evaporation tubes 313 on the two sets of sliding rods 1-302 and the rotating rod 1-303, the motor 2-504 can be started, so that the motor 2-504 drives the pulley 3-505 to rotate, thereby driving the pulley 4-506 to rotate. When the pulley 3-505 and the pulley 4-506 rotate, through the cooperation of the limit groove 509 and the limit block 510, the pulley 3-505 and the pulley 4-506 drive the two rotating rods 2-307 to rotate through the sliding rod 508 and the limit block 510. When the two rotating rods 2-307 rotate, with the centered sliding seat 2-311 as the center, the sliding seat 2-311 located above the centered sliding seat 2-311 moves upward under the action of the thread of the upper thread 308 and the limiting action of the sliding rod 2-306. The sliding seat 2-311 located below the centered sliding seat 2-311 moves downward under the action of the thread of the lower thread 309 and the limiting action of the sliding rod 2-306, performs the same synchronous variable pitch as the sliding seat 1-310, and increases the distance between multiple evaporation tubes 313. On the basis that the distance between the evaporation tubes 313 on the sliding rod 1-302 and the rotating rod 1-303 becomes larger, this realizes that the distance between the evaporation tubes 313 on the sliding rod 2-306 and the rotating rod 2-307 becomes larger, that is, the outer evaporation tubes 313. The evaporation tubes 313 of the inner and outer two paths can be misaligned in the vertical direction while also increasing the distance between multiple outer evaporation tubes 313, so that the hot air flow blown into the boiler 2 by the cooperation of the fan and the burner can better heat the inner and outer double-pipeline evaporation tubes 313, improving the efficiency of steam generation.

[0054] Dislocation lifting:

[0055] On the basis of the variable pitch and dislocation of the inner and outer double pipeline evaporation pipes 313, the electric telescopic rod 304 can be started, so that the electric telescopic rod 304 pushes the lower ring two 305 upward, so that the two rings two 305, the two sliding rods two 306, the two rotating rods two 307 and the sliding seat two 311 and the evaporation pipe 313 on them move upward synchronously. During this process, the sliding rod 508 and the limiting block 510 are fixed under the connection with the pulley three 505. The ring two 305 and the rotating rod two 307 move upward, so that the sliding rod 508 and the limiting block 510 partially slide out of the sliding groove 507 and the limiting groove 509, and under the limiting cooperation of the limiting groove 509 and the limiting block 510, the sliding rod 508 can still drive the rotating rod two 307 to rotate when rotating, and the distance between the evaporation pipes 313 on the sliding rod two 306 and the rotating rod two 307 is adjusted. Under the action of the synchronous upward movement of the two rings two 305, the two sliding rods two 306, the two rotating rods two 307 and the sliding seat two 311 and the evaporation pipe 313 on them, the evaporation pipes 313 on the two sliding rods two 306 and the rotating rod two 307 are further misaligned with the evaporation pipes 313 on the two sliding rods one 302 and the rotating rod one 303, avoiding the mutual crossing positions of the inner and outer circles of evaporation pipes 313 from blocking the heat transfer, and improving the heating effect of the hot air flow sent by the burner and the fan into the boiler 2 on the evaporation pipes 313 again. When the input power of the burner and the fan is fixed, the evaporation efficiency of the water flow in the evaporation pipes 313 can be improved, and the energy-saving effect can be achieved. And when the outer pipeline is out of use, the evaporation pipes 313 on the outer pipeline can also be moved to avoid the evaporation pipes 313 on the inner pipeline, ensuring the heating and evaporation effect when the inner pipeline operates alone.

[0056] The above are only the embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
